Purpose The purpose of this paper is to study the dual solutions ternary hybrid nanofluids stagnation point past a linearly shrinking sheet with second-order slip conditions. nanofluid consists in alumina (Al_2 O_3), copper (Cu) and titanium dioxide (TiO_2) embedded as nanoparticles water (H_2 O), base liquid. Design/methodology/approach flow over stretching/shrinking surface has wide range applications engineering several technological purposes, such as, extrusion polymer melt-spinning process, extrudate from die generally drawn simultaneously stretched into which then solidified through quenching or gradual cooling by direct contact water, large metallic plate bath, etc. Using appropriate transformations, full partial differential equations, continuity, momentum energy, were transformed nonlinear ordinary equations that are, then, solved numerically using bvp4c function MATLAB software. Findings effect governing parameters on skin friction, heat transfer, velocity temperature profiles been analyzed graphical tabular reports. It found (upper lower branch) exist for some values parameters. From stability analysis, it upper branch solution stable physically realizable practice, while unstable and, therefore not practice. Both branches, reduced transfer are graphically tables presented. friction (or shear stress), substantially affected slip. Originality/value present results original new surface, they successfully extend problems open literature.

Abstract Nanofluids (NFs) have been implemented in several areas to increase heat transfer efficiency. Thus, efficiency for energy can be achieved. In this study, the effect of nanoparticle (NP) type, volume fraction, and Re number on NFs were analyzed numerically, statistically, theoretically. Heat coefficient, units, wall shear stress, friction factor selected as NFs. ANSYS Fluent software was utilized carry out computational fluid dynamics analyses. The numerical calculation scheme by employing Taguchi L9 orthogonal array with three decisive factors. NP assumed factors levels. Signal-to-noise ratio analysis determine direction impact ideal levels each Significance contribution rates calculated Analysis Variance. According mathematical responses, most effective NPs h τ w identified Gr, Al 2 O 3 , Cu, respectively, whereas units are found respectively. addition, from 6,000 8,000 causes an a decrease NTU f . data achieved research may guide paper experimental

<div class="section abstract"><div class="htmlview paragraph">Nanofluids have emerged as effective alternatives to traditional coolants for enhancing thermal performance in automotive applications. This study conducts a comparative analysis of the viscosity and conductivity ZnO Cu hybrid nanofluids. Nanofluids were prepared with nanoparticle concentrations 0.1%, 0.3%, 0.5% by volume characterized over temperatures ranging from 25°C 100°C. The results demonstrate that nanofluids achieve an increase up 22% 28%, respectively, compared base fluid. Concurrently, these increases 12% at highest concentration temperature. addresses critical research gap investigating combined effects nanoparticles nanofluids, area has been underexplored. By providing new insights into optimizing both viscosity, this contributes development more efficient cooling systems applications.</div></div>
